Designed for better players, the KBS Tour 90 shaft was engineered with ‘moment of inertia analysis’ to increase stability from ‘grip to clubhead’ to enhance the results of well-executed swings. By reducing the mass and radius of each step in equal proportions along the shaft’s center line, the KBS Tour shaft delivers optimum stability resulting in efficient energy transfer from the player’s hands to the clubhead. In addition, the KBS Tour shaft incorporated step-by-step Moment of Inertia analysis to reduce shaft ‘interference’ during a player’s well-executed swing.
